Glenn

A jury convicted James Glenn of two counts of committing lewd and lascivious acts on a minor (Pen. Code, § 288, subd. (a)), one count of attempting such acts (Pen. Code, §§ 664/288, subd. (a)), and two counts of indecent exposure (Pen. Code, § 314, subd. 1). He was sentenced to prison and appeals, claiming that there was error in the constitution of the jury, that the evidence was insufficient to sustain one of the counts, that certain physical evidence should not have *620 been admitted, that the trial court should not have denied his motion for a transcript of his earlier trial, that he should not have been subject to impeachment with a prior conviction, that testimony of an expert was improperly admitted, and that jury instruction error occurred. We reject his contentions and affirm.

Facts

Glenn entertained the three victims, preadolescent boys, in his apartment by showing them sexually explicit films on his VCR. He touched one victim on his penis, attempted to do the same to another, and touched the third on his behind. Glenn also exposed himself and masturbated in the boys’ presence. These acts occurred on various dates during the summer of 1988.
